Optimization of a New Design of Molten Salt-to-CO Heat Exchanger Using Exergy Destruction Minimization.

One of the ways to make cost-competitive electricity, from concentrated solar thermal energy, is increasing the thermoelectric conversion efficiency. To achieve this objective, the most promising scheme is a molten salt central receiver, coupled to a supercritical carbon dioxide cycle. A key element to be developed in this scheme is the molten salt-to-CO heat exchanger.
